Question

使用 httpurlconnection 写入大型视频文件时出现问题。

响应代码在这里

final InputStream is = connection.getInputStream();
            final ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            final byte[] buffer = new byte[maxBufferSize];
            int bytesRead;
            while ((bytesRead = is.read(buffer, 0, 1024)) != -1) {
                bytes.write(buffer, 0, bytesRead);
            }
            log.log(INFO,
                    format("{0} took {4} ms", url,
                            (currentTimeMillis() - start)));
            String response = new String(bytes.toByteArray());

如果你使用的是OkHttpClient，检查一下，这里有一个参数retryOnConnectionFailure(false)。默认情况下它是 false，你只需将它设置为 true 然后错误将被删除。希望因为我有同样的问题并解决只是改变它。

OkHttpClient client = new OkHttpClient.Builder()
    .retryOnConnectionFailure(true)
    .build();
